FASTENING DEVICE FOR TYPE-WRITER COVERS.

SPECIFICATION forming part of Letters Patent No. 657,194, datedSeptember 4, 1900. Application filed February 25, 1899- Serial No.706,839. (No model.)

To all whom it may concern:

Be it known that LWILLIAM R. FOX, a citizen of the United States,residing at Grand Rapids, Michigan, have invented certain new and usefulImprovementsinFastenerDevices for Type-Writer (lovers, of which thefollowing is a specification.

My invention relates to locking devices for the covers of type-writingmachines in which :0 a sliding bar is made to lock the cover to the baseon both sides.

The invention is illustrated in the accompanying drawings, in which-- 7Figure 1 is a perspective View of the lock- '15 ing-bar. Fig.Zisasectional View through the base-board and a part of the casing orcover, and Figs. 3 and 4 are detail views.

In this invention I have sought to avoid the slotting, and therebyweakening, of the edge of the cover, and, further, to provide aconstruction such that the cover may shut down well over the base andthe locking-bar may be completely formed and then put into place and beretained securely. The base,

of otherwise ordinary construction, is provided with a transverse grooveor seat underneath, having an open slot at one end for the reception ofthe locking-bar. The grooveis shown at 3, and it is fitted to receivethe bar 0 and permit it to be freely moved from side to side. One end ofthe bar is turned upward and inward to form a bolt 6, which when the baris pushed into locking position passes through a hole 13 near the edgeof the cover 3 5 and into a short groove 15 in the upper face of thebase. This forms the lock on one side. The other end of the bar isturned vertically, as shown at 7, and from the upper end projectshorizontally outward to form a bolt.

As shown at 8, this is in the form of a loop 11, fitted to receive alatch. I have also shown this loop as formed with a lateral bend and anarm 9 in the same plane as the part 8, but extending farther inward.

5 This front end of the bar is fitted to recesses or slots in the edgeof the base. A vertical slot at receives the upturned end 7 and is soproportioned to the bar that the said bar may be pushed to allow theloop or looking end of the part8 of the bar to lie within or flush withthe edge of the base, and the locking part of the other end of the barwill stand off at the same time to permit the cover to be shut down atboth these edges. This is illustrated in Fig. 2. 'A- shallow recess ismade in the upper surface of the base, as 'shown at 12, to receive theloop or looking end of the bar and allow it to lie flush with thesurface. An inspection of Fig. 2 will show that when the baris moved theend 6 will enter its hole in the edge of the cover, and at the same timethe locking end 11 will pass through the hole 14.

in the opposite edge, thus locking the cover down at front and rear. Alatch 10 on the cover may retain the bar in place, as shown in Fig 4:.The lateral arm 9 rests upon the base and holds the bar in place andfrom the loop of the locking end. The bar may be formed into its propershape and then placed on the base. The front and rear edges of the baseare rabbeted to form ledges 2, on which the edges of the cover rest,these being pro= portioned to bring the holes in the cover into" linewith the'bolts, the ledges being of course below the plane of the holesin the edge of the cover in place. The low position of the locking-barallows the cover to shut well down over the base.

I claim 1. A locking-bar having upturned ends, with bolts thereon, onebolt projectinginward and the other outward, combined with a base havinga seat in the under side adapted to receive said bar and permit it toslide there= in, and a slot at one end adapted to receive the upturnedend of the bar carrying the outward-extending bolt, and combined alsowith a cover having bolt-holes therein, the parts being proportionedand. arranged substantially as described. 9o

2. A locking-bar having upturned ends, with bolts thereon, one boltprojecting inward and the other outward, and laterally bent to form aloop, combined with a base having a seat in the under side adaptedtoreceive said bar and permit it to slide therein and a slot at one endadapted to receive the upturned end of the bar carrying theoutward-extending bolt, and combined also with a cover having bolt-holestherein, the parts I l a I being proportioned and arranged substantiallyas described.

3. A locking-bar having upturned ends, with bolts thereon, one boltprojecting inward and the other outward and laterally bent to form aloop, combined with arabbeted base having a seat in the under sideadapted to receive said bar and permit it to slide therein, and a slotat one end adapted to receive the upturned end of the bar carrying theoutward-extending bolt, and combined also with a cover having bolt-holestherein the parts being proportioned and arranged substantially asdescribed.

4. In combination, the cover, the baseboard having rabbets orprojections to prevent the cover from passing entirely over thebase-board and the single locking-bar therefor extending across saidboard parallel with said rabbets, substantially as described.

5. In combination, the cover, the base board having alocking-ba'r, saidbase-board having rabbets or projections near its bottom side to preventthe cover from passing entirely over the base-board, said locking-barextending across the board parallel with said projections, and bolts ateach end of said bar in a higher plane than said rabbets adapted toengage the cover, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

\VILLIAM R. FOX.
